Idea Exchange: Use gauze to help keep pulse oximeter probes in place in exotic and wild animal
Treating nontraditional species, such as opossums, can create challenges in using equipment designed for domestic species. To help pulse oximeter probes stay in place, I wrap a thin piece of wet gauze around the probe site, whether the tongue, toe, or ear. The moist gauze is thin enough to allow for a good reading, and it provides extra friction to keep the probe from slipping off the patient.
